|Advantages and disadvantages|
The devices are comprised of an outer coil containing mostly nickel and an inner coil of carcinogenic PET fibers. The coils are fragile and break easily. Heat degrades the coils and ablation therapy is not recommended, but frequently used due to the increased pain and menstrual flow that comes with essure.
Small, flexible inserts are placed into the fallopian tubes by a catheter passed from the vagina through the cervix and uterus. The insert contains inner polyethylene terephthalate fibers to induce benign fibrotic reaction and is held in place by flexible stainless steel inner coil and a dynamic outer nickel titanium alloy coil. Once in place, the device is designed to elicit tissue growth in and around the insert over a period of three months to form an occlusion or blockage in the fallopian tubes; the tissue barrier formed prevents sperm from reaching an egg.
Unlike other forms of tubal ligation, no general anaesthetic nor incision through the abdomen is required.
For the Essure method, three months after insertion a Radiologist physician performs an x-ray procedure called a hysterosalpingogram to confirm that the fallopian tubes are completely blocked and that the patient can rely on the Essure inserts for birth control. A contrast agent (dye) is injected through the cervix, and an x-ray technologist takes photos of the Essure coils to ensure no contrast leaks past the Essure.
The reported insertional failure rates are "failure to place 2 inserts in the first procedure (5%), initial tubal patency (3.5%), expulsion (2.2%), perforation (1.8%), or other unsatisfactory device location (0.6%)". Upon follow-up, occlusion is observed to have occurred in 96.5% of patients at 3 months with the remainder occluded by 6 months.
Cautions and warnings
The inserts do not prevent the transmission of sexually transmitted diseases. The procedure takes about 10 minutes for a trained physician to perform and can be performed in a physician's office. General anesthesia is not required. Unlike many temporary methods of birth control, the Essure inserts do not contain or release hormones.
The inserts are made from polyester fibers, nickel-titanium and stainless steel and solder and are safe to use with MRI equipment. The Essure procedure is reported to be permanent and not reversible by the manufacturing company. Notwithstanding the manufacturer's position, several Essure reversals have been performed.
- Perforation, expulsion, or other unsatisfactory location of the insert
- Pregnancy and increased risk of ectopic pregnancy
- Pain, cramping, vaginal bleeding, menstrual pattern changes, light periods at first then longer, heavier periods lasting up to 6–8 weeks due to changing birth control methods to a non-hormonal solution
- Vasovagal response (fainting)
- Allergic reaction to the materials
- Heightened allergic respone to other allergens
- heavy metal toxicity
- itchy, raised rash
- brain fog
- autoimmune disease symptoms
- weight gain
- hair loss
In 2013, the product made news with women complaining of severe side effects leading to surgical extraction. According to one article, women who have gotten pregnant are naming these children e-babies. There is a Facebook group of over 6,000 women, as of March 3, 2014, titled Essure Problems. Erin Brockovich also hosts a website where women can share their stories after having the procedure.
